Usage and Features

MQ8260A crankshaft grinding machine is intended for use in automobile, tractor and diesel engine repairing shops to regrind the crankpins and journals of crankshafts. Wheelhead rapid approach and withdrawal is hydraulically effected, the worktable is operated approached either by hand or by power. Power table traverse, either left or right, is momently actuated by depressing and releasing the electric push button in connection with the desired direction. This arrangement facilitates table spacing for the grinding of the next journal of crankpin.


  • Four different work speeds are obtainable by making use of a double- speed motor and the belts in workhead.
  • Union chucks are used in the headstock and tailstock of adjusting eccentricity up to 120mm.
  • Friction coupling is used in the headstock transmission chain for its easy adjustment.
  • Table longitudinal traverse is operated either by hand or by power.
  • Wheelhead rapid approach and withdrawal is effected by hydraulic means.
  • Rolling guidways are used on wheelhead dn made by high quality material. The wheel spindle being of 80mm in diameter has good rigidity and strength.
  • Plastic coated bed ways with less friction.
  • The bed ways and wheehead ways are lubricted in automatic cycle by means of oil pump.
  • The digital display device can be optional.
